Your cart is empty.The missing piece of the increasingly popular early-GM transmission swap!
With late-model GM transmissions containing an internal speed sensor outputting 128,000 Pulses Per Mile, the stock 40-tooth (40 pulse per revolution) reluctor ring provided the factory ECM with a high frequency input. The SEN-01-128 can now recreate this missing high frequency rate when converting to an older style transmission with a mechanical speedometer output.
With a standard female 7/8” thread-on fitting, the SEN-01-128 fits all GM transmissions with a mechanical speedometer cable outlet. Removable weather-tight 10’ cable provides for simple installation and cable routing. 128,000 Pulse Per Mile Square Wave signal output is direct replacement for the stock GM internal speed sensor, allowing the ECM receive the signals it needs for proper operation.
Fits GM transmission models with 7/8” Male Threading, ie: TH350, TH400, 700r4, 2004r, etc.

It made it roughly 30 miles before stripping out inside the sensor. Before that it worked great and solved my speedo problems. Idk if they'll warranty it but I'm not holding my breath.

This was a replacement for the one I broke when I was reinstalling it after rebuilding the transmission. I didn't get the shaft aligned well and it became damaged to the point that it did not function. I have now installed Dakota Digital Dashes in three of my restomod builds. Great products, very well made and come with well written instructions. This is the only part that I have had fail, and it was entirely my fault.
